Abstract

We have designed, synthesized, and investigated a self-assembling supramolecular system which mimics, at a molecular level, the function performed by a macroscopic electrical extension cable. The system is made up of three components, 1 2+, 2-H3+, and 3. Component 1 2+ consists of two moieties: a [Ru (bpy) 3] 2+ unit, which plays the role of an electron donor under light excitation, and a DB24C8 crown ether, which fulfills the function ...
